It’s Hump Daaaaaaaaay (I’m never going to get tired of that, so I hope you don’t either).
I agree with this completely. Sure, there are a lot of influencing factors that affect who you are. But, like it says, at the end of the day, the final product is up to you and you alone. Nobody else can make you or keep you from doing anything. You have the power to be what you want to be. Use that power wisely.
