Hey Akash how are you doing today?
Akash to be successful you don't have to set yourself up for success, rather you've to be careful not to set yourself up for failure.
You do that a lot by overpromising. No you're not going to be able to do this consistently for the 7 days, or a month or whatever. Your present you is trying to relish on the future glory but that glory has not been achieved yet. Usually this is fine when you need some motivation but a lot of the times the present you does not want to do the work, it just relishes in this potential glory.
Just focus on getting today's work done and let the future you take care of himself!
Thanks, have a lovely day my friend
Akash
