Welcome to the world of go!
You should play as much as you can with your friend, Mr. Yang. You will learn a lot from him.
Several comments on the early game:

;B[qp]C[*** See variation.]
;W[pq]
(
;B[ql]C[*** I wondered about this move. Maybe you have read that you should make this extension from two stones. That is for a different situation, one where you do not already have a stone in this area, and one where your two stones are not so weak. One hint that they are weak is the number of dame they have, only four. Fewer than 5 dame is a danger signal. See variation.]
;W[op]
(
;B[rp]C[*** Good instincts! This not only protects your two stones, it threatens to go into White's corner. See variation.]
;W[qf]
(
;B[rd]C[*** Again, good instincts! You protect the corner while attacking White. See variation.]
;W[qi]
;B[qj]

;B[oi]C[*** Good! Hane at the head of two stones.]

;B[ok]
;W[mj]
;B[nk]
;W[nc]
;B[dj]C[*** Good instincts! A lot of people would try to save the stones in the top right corner, and only end up making White strong. Your willingness to sacrifce the corner bodes well for your advancement.]
;W[qc]
(
;B[hq]C[*** See variaton.]
;W[jd]
;B[cg]
;W[fd]
(
;B[ef]C[*** Unlike your sacrifice of the top right corner, here White is not so strong, and Black is. In additon, this move is not big, so you get little for the sacrifice. See variaton.]
;W[ec]
(
;B[dm]C[*** Poor instincts. You are just nailing down some territory. Better to nail down territory by fighting. See variation.]

(
;B[gf]C[*** Go ahead and sacrifice the single stone.]
;W[hd]
;B[jj]L[mi]C[*** But then make a large framework. White can invade, of course, but Black should end up with the bulk of the territory. Remember, make territory by fighting. Also, this move threatens the indicated cut at N-11. The resultant fight is complicated, so, as a practical matter, Black should perhaps not make it right away, but it is a play to keep in mind.

;B[oj]L[nh][ph][qh]C[*** This play not only saves the Black stone, a minor consideration in itself, it threatens cuts at the indicated points. Hmmm. The points do not show up. They are O-12, Q-12, and R-12.]

(
;B[nh]C[*** At this point in the game the center is more important than a few points on the second line. For one thing, because of the strength Black already has on the side, he can afford to make such an enterprising play. ]
;W[og]
;B[ni]C[*** Black is quite strong towards the center. We call this play thick. Thick is good. Black will not necessarily make territory in the center, but is prepared for further fighting.]
)
)
(
;B[qe]C[*** This attack is called a kick.]
;C[*** It induces this play, which makes White heavy. White has invested another stone, and it is more difficult to throw these two stones away than a single stone. ]W[pf]
;B[nd]C[*** Black continues the attack while making what is nearly territory.]
)
)
(
;B[cf]C[*** Saving two stones in the bottom right corner is not big, since White is already strong there. Better to attack White here now.]
)
)
(
;B[op]C[*** This strengthens your stones, and threatens the White stones. It would be very good for White to play here, which White did in the game. At this point you may not see the Black threat, but you can see that the two White stones in the corner have only four dame. For the threat, see the continuation after White passes.]

Main points:
Your willingness to sacrifice is very good.
You will go far.
But you need to show more fighting spirit. Don't just try to nail down territory by yourself. That is very inefficient. Attack White, threaten to attack. Make territory by fighting.
Good luck!
