Desire

"When you want something in life , you gotta be relentless"

This phrase is a reality, if you want something, no matter how hard it is to attain, the first step it is to blindly believe that you can have it. You need to put on your visors, to get all the negative distractions out of the way so that you can only see your aim. If someone tells you to have a plan b, just in case it doesn't work out, and you think about it you will eventually end up acting on your plan b because it will be more easy and attainable than plan a, so your mind is going to go for the easiest route and you are going to fail to achieve what you wanted in the first place. Because if you are thinking of other options if you are being doubtful, you have already given in. Don't give in. I repeat, do not give in. It is possible, but only if you want it to be possible. You need to see it happen in your mind, to see it happen with your eyes.
So start imagining how it is going to be, how you will feel when you have it. Sometimes the devil on your shoulder will try to convince your mind that it is not possible, that you don't deserve it, don't listen to him, he is bullshit.
You see when people want something they dream about it all day and night and imagine how it will be when they attain it, so they come soo close to achieve it in the physical world and then, doubts start infiltrating their minds. They start thinking like "this is not going to happen to me, I am not lucky enough" or " oh I don't deserve this". Well, you affirmed it and boom, on the verge of making your wish come true people themselves sabotage it and blame their "luck" or "other people".

That is where you need to correct yourself, even if you are doubtful if those thoughts come to mind, plan b thoughts etc. Let them go. Please, stick to believing yourself and affirming that you can, control your thoughts and thinking nothing other than achieving what you want to. And eventually, you will. Just believe, there is a lot to you than you think.
