It's never too late!

The reason why we live is to test every little new activity that we can include in our schedule. But let's think in both directions: Do we know how to mingle extra-activities with school or work?
Almost all of the answers are that without a perfect ordnance of the schedule nothing of that will work.  Well, one other hand, is that we are never the best in something. Moreover, we can easily find other new theories that we haven't even heard about by then.

As a conclusion, (towards life or even towards childhood) you shouldn't focus on only one thing. There are a lot of other things that you should try at every age.:)
