You need a few things to free yourself from the chains of addiction!
1. The ability to plan other activities that can stimulate and amuse your brain comes from the
imagination you have to come up with them.
2. If you say that "this game is so addicting" then what you need is a little push on this thing called
will that we all have in greater or less measure!
3. Surely, osu! must take a lot of your time if you took the time to create a thread in OT (of all places) asking how to stop your addiction.
Look for more activities that you might like. Time doesn't wait for anyone, and once it passes you never get it back!
