It sucks missing and failing over and over again. But why do you fail again? why do you miss it again? It is because your mind is conditioned to fail again.
What the mind sees over and over again will make it believe it and make it expect that it will happen again. That is why you are failing, that is why you are missing. You already think that it will happen before it happens.
So what you need to do is think that the next one will work, think that the next try will go in. And even if you miss, even if you fail again... just think that next time you will succeed. That mindset will keep you going, it will make you excited, it will give you motivation because you know you will succeed next time.
If you are applying for a job and you are on a streak of not getting hired...just keep on trying, always have an expectation that your next try will be successful. Think that next time you apply, the contract will be given to you on the same day. It will become real if you think that it's real. Your mind is like a magnet, it will magnetized situations that you are thinking and make it real.
So if you are continuously failing and you feel like the world is cursing you, be aware of what is going inside of your head. Maybe you are thinking a lot of negative things. Maybe your mind is already programmed for failing, you should replace the software of your brain, rewire it so success.
Visualize the win. This shit is effective, visualization has been thought a thousand times yet people are not doing it. It will not work if you don't believe in it. Remember, your purpose is to change the thoughts in your head so visualization is a good process to do it. And even if you don't believe that it will not work, remember that your purpose is to simply change the negative thoughts to positive ones, just try it, see yourself winning, see yourself succeeding and you will see that it will happen. This is not some kind of a magic or something, voodoo has nothing to do with it. It is simply unlearning the bad experiences and putting some good shits inside of your head.
Self talk inside of your head. If visualization is hard for you to do, then self talk inside of your head is a good one. Just simply say "I am successful, I am successful". Repeat this inside of your head as many as you can everyday. You can use any words that you want, it is up to you. Make sure the words that you will use are positive and will give you hope. Repeat the words until you believe it. There is no harm in trying, there is a big in experimenting.
