I’ve a feeling that you have this habit but still somehow you manage in the end, people who are in this habit can produce better and can get good concentration only under pressure. Beside negative impact of this habit the positive side is that it saves from stress, tension and depression kind of stuff.
I can say all these things because i suffered from this and tried yoga, hypnotism and many other things but even could not perform them well because even before starting i started dreaming myself at the apex of these field:)
It is very hard to eliminate it suddenly may be you can do it in a long run but i hope thAt it’ll not harm you much just need to make your will strong. A will that you must have to get to the destination then the suffering of the journey won’t have that much impact on the results.
Some suggession
- Try not to sit in front of books all day long rather make it in short span of time like 2 hours and then a break will increase productivity.
- I also feel that after going into bed you take longer time to sleep, just make sure that try to make keep your brain empty, free from all kind of thoughts, try to do it as much as possible it is a good cure.
All the best:)
