Advice Needed How to force myself to finish a project

Hey mate,
2 possible approached I can think of
I use this one mostly:Just do the got damn start.It's basically the same behaviour as when you go hit on someone.Go in there,no questions asked,no backsies,don't think why and do it swiftly.You will get absorbed at such an extend,that time will fly.(Usually,a deadline helps me go into high-gear.Such projects have no clear and pressing deadline.So try to think some way to punish/reward yourself for failing/meeting a self-made deadline)
Have someone push it to you,go do it as soon as you read this post etc.The point is you need to sit in that chair and work for even 1 minute.Then the magic will take place and you will try to solve the problems that arise with your app.

2nd approach:Fake it till you make it.
