sometimes taking on too much...

I was driving through town yesterday and i saw a little boy trying to ride a bike. What caught my attention was that the little boy was so very little and the bike was so very big. The child obviously thought that he could handle such a big bike, and maybe he even was proud of himself for propelling such an object that was so much larger then himself... but to me, it was so very obvious at how much he was struggling.
 And then i thought about life (as i do often). I thought about how we look at things and how we want things... but sometimes those things are too big for us. And when we try to take on those big things, we struggle and try not to fall. We try to make it seem to others that we can handle whatever the big thing is in our life. But in reality we may need to grow first before the "bigger bike" fits us. We need to ride the smaller bike and gain skills and let time pass before we take on the bigger bikes. We are surrounded by a society that thinks that the bigger bikes are more desirable.. but in the end, we end up just looking silly trying to ride these over sized bikes, and it gets so EXHAUSTING!
Do you have any "bigger bikes" that you are trying to take on when it's just not the right fit?
