If you need to take action or make a decision but you are not sure about it then you have to go with your instincts, if you feel good about it then go for it but if not... then leave it alone and do some other thing or check some other options.
There is a saying that you still have to try even if you already knew that you've lost. For example, if you are looking for a job and the security guard on that company already told you that there is no vacancy or job opening, you still need to pass your resume if your instincts is telling you that you still have a chance. Pass it if you feel like passing it but if not then just leave it and look for another company that is hiring.
If you feel that you have a chance and you can succeed then go for it but if you don't feel it anymore and there is no excitement then what is the point for doing it?
The key here is to always feel excited, always feel hopeful. You can control your emotions, you just need to motivate yourself. Because if you can always feel good about something then there is a very big chance that you can get what you want.
But if you feel sluggish, lazy and unmotivated then for sure you will fail. The law of attraction will not give you attraction, it will just ignore you.
You have to know how you feel but sometimes emotions are tricky. Sometimes you want it but you already feel tired. So it is your job to find the excitement, it is your job to bring the joy back so you can produce awesome results and make correct decisions. It is your duty to look for the fun in what you're doing.
You need to draw the state from within, you need to build your emotions and make yourself always excited. It is very simple, just remember what you want and visualize yourself already having it.
