How should I have approached this formation?

Hello all,

I just finished a game where both my opponent and I occupied opposite sides of the board. In the game I wanted to play on one the left hand side after the 8th move. I couldn’t make up my mind on a strategy, so I made a foolhardy attempt at approaching inside my opponents stones. I never really felt like it was a good idea but I wanted to try something new :P. I came away from it living, but feeling like I shouldn’t have.

Anyways, specifically I’m asking for some general ideas of how to approach the situation that came about after the 8th move.

Here’s the game: https://online-go.com/game/7280688
