Build what you need
In the previous post I mentioned that you can talk to people and build things to help solve problems.
But there is another way. Create something you need.
Even if you think it's been done a 1000 times. Your version of the thing is valuable. Especially if you care about the quality.
In the process of building it, you will find out more things than you knew before.
Even if it is a notepad. Or a new mouse trap. Build it.
