It is OK to dream big, to make long term plans to take a few days off and schedule all the things you have to do. More thinking will short the time of the execution, and definitely help you to achieve the next step even easier. The plan let's do things now and think later about mistakes and consequences, is not a plan. It is a disaster waiting to happen. You have so little to lose and so plenty to gain to just sit down and think things over one more time before you plunge into the sea of the variables.
You don't feel well, you are tired and exhausted, but think now is the best time to thoroughly think over your most important things in life - because you are of no good for everything else? Please don't! That is the worst time to think things over, because your negative energy and lack of concentration will influence negatively your decisions. You will not chose the most efficient option, but the one that just looks like it is the best. People usually think that the hardest one is also the best, so they work themselves into the oblivion.
How to avoid overworking is maybe the biggest problem. You can't think with the blurry brain and overwhelmed mind. Nothing good will come out of that fruitless marriage... That is why exactly you need enough rest and then time for yourself, even more than it is expected, or that somebody else might advise you. Your personal happiness is not measured in dollars, so maybe you will need to make some sacrifices on that department, who knows... The more you work, the lesser the money you have - you will say. That is correct, because you loose sight where it went or how you spend it.
People tend to spend more and be careful less when they are in chaos,. tired, sleepy, dissatisfied or other. Money just rains through them without them feeling the benefits of their work - and very soon the work becomes the slavery. It is OK to work a lot, but never forget to rest a lot. Invest into that and planning too. Dream big but also make everyday things easier on yourself.
