Force yourself. That is something that not many people do but if you are going to work long term then you should be forcing yourself. You are having trouble waking up early? Force yourself to wake up early, too early if you have to, that way you will go to bed early as well, having trouble finding food to eat, or can't decide? Force yourself to eat healthy, having trouble exercising? Force yourself to do it.
If you keep doing these for a couple of weeks in a row every day, it is going to become your regular day and it won't really take that much time neither and rest of the time you could relax. I have been working remote for so long and never been happier in my life.
There are always adjustments in every first times. It’s up to us how we can adopt in it and live with it, rather than focus on complaints and believe that it’s not gonna work anymore. Like when this pandemic hit us, working remotely has become a trend and I must say, it has worked for me after dealing on several adjustments. However, I believe that there are also some of us who never achieved their goals and end up in failure because maybe their environment is not conducive for working and if you have small kids around, they can really destruct our focus and left us working the hard way, the reason why some turn to be ineffective in their own works or jobs.
