Create a list of tasks you could finish in 5 minutes

Why you should create such list? We often have some time gaps between major tasks. Having nothing prepared to work on you will waste that time. So what we could do? Make a list of things that could be done in five minutes or less.

After that, prepare everything in order to work on such tasks (notebook, pencil, pda, ...).

Learn to recognize such time gaps and fill it with some useful work.
