But starting fresh might be a solution to this issue.
Doing a lots of research before investing time on it is one the clear way to start fresh. A plan must be made after doing the research; a plan that includes target at specific time.
Starting fresh needs a lot of motivation as well which should come from within not outside (must of us have the opposite).
So, starting fresh is the solution to many of the problems we face these days.
