Trying out your ideas to do one thing or maybe even a way to improve something.
Doesn't have to be a complete idea all the time; mainly you need to build yourself hands-on experience of trying to solve a problem, the more you do the more ideas you get as well as the wisdom of why some methods may not work.
Sometimes I think of stupid ideas, but even thought I'm pretty certain it wont work, I will try it out just to see anyway. Many times such attempts leads me to other ideas.
Also if you are stuck, do some research, sometimes you will find a solution, others solutions might lead you to other possible methods. Just keep trying stuff.
