Here some thing which works for me:
1.) Go play outside with your friends atleast for an hour, blogging isn’t so important. Health is the most important thing in the world.
2.) Don’t sit in one position whole day. Try to use laptop in different position like sitting on chair, laying on bed on stomach side, laying on bed on back side or using a small or large table.
3.) Drink lot of water which force you to leave laptop in every half hour for peeee…
4.) Don’t place screen to too close to your eyes. My most of friends have glasses but I don’t have because I don’t use laptop, mobile and T.v like them. They use these think without blinking eyes most of times which is dangerous.
5.) If you’ve laptop then change place regularly. Like I would like to use it my study room some time, sometime is guest room, sometime in lobby.
6.) Stretching is the best technique to overcome laziness.
7.) I can’t adopt it but you can. Wake up early in 6:00 A.M and do yoga then focus on most important thing.
8.) Watch movies, play games and learn new things also
Some of above works for me while other works for other blogger.
