I tried to be thorough. It might be a bit overwhelming, but just try to get some of the concepts as best as you can.

(;W[bp]WL[1784.772]C[This move gets you a bit of territory and later, it might undercut black a bit, but it is very weak towards anything going on in the center and barely affects the left side. So it is small early on. You want to be able to affect more of the board than the bottom left corner area. ]

;W[ci]WL[1759.038]C[This is good in that it attacks black's stones while building up your potential. ]
;B[df]BL[1752.416]C[So black wants to fight it out. His stone loosely surrounds your stone and your stones loosely surround his. Neither is tightly surrounded, so none will have trouble living at this time, but they do break up the potential territory. ]
(;W[cf]WL[1751.174]C[Unfortunately, attaching to his somewhat weak stone invites it to strengthen. This might be ok if you want to leave that stone for aji and take some points. Then it won't be easy to kill your stone, but I think this is questionable because the move I suggested forces him to strengthen himself while you strengthen yourself. And it takes profit in the process. It's usually better to not attach to a weakish stone because you want it to stay weakish. ]

(;W[fd]C[This move is good because it pressures the black stone. Now black approach from that side and so his stone is weakened a bit. This in turn strengthens your lone stone. Of course it's black's move and a play that strengthens his lone stone would weaken your lone stone.
This is kind of the give and take of go. ]))
