Who said change is easy? It is not! Have you ever tried to stop smoking or known someone who has tried? It is tough and many people fail! People want to stop but in many cases it is simply not working.
This applies to most big changes (e.g. move to a new place, start your first big project, start a new job) in your personal life as well as to big changes in your professional life. If these big changes would be so easy then everyone could do it easily.
One way to get through big changes is to decide upfront how strongly you want to achieve a goal and if your discipline is strong enough to actually do it. You really have to want that change and be ready to go the whole nine yards to achieve it. If you try to change without a real good reason and without much conviction you've already lost. Once you successfully mastered a big change it is very rewarding but you have to be willing to but in the effort to get there.
