IN ORDER TO BECOME SUCCESSFUL YOU MUST DISAPPOINT A LOT OF PEOPLE

It is what it is, you must become a dream crusher if you want to become successful. If you want to become a very good musician or an an artist then you must disappoint the dream of your parents for you of becoming a doctor or something.

If you want to become a superstar in your team you must take the risk and disappoint your coach for not following his orders, because if you will not do it then you will be in the same situation forever. You will not shine, you will not standout because you're following the system forever, and if you're following the system... you will not be able to express yourself.

You disappoint your friend because you didn't go to his party because you have some important things to do... it is ok because you want to become great, you really need to make a sacrifice if you want to become successful. This not bad, you have to become hard, don't go soft or else you will not achieve what you wanted to achieve. Just say sorry because you can't make it. I am very sure your friend will understand it especially if it has something to do with the transformation of your life.

You can also miss your sibling's birthday because you're trapped in a special project or something, there is a big chance that it might happen. But what can you do? you can't leave what you've started, you have to act like a professional.

Because what they feel is none of your business, they can handle their feelings if they are mentally strong. Don't feel guilty if you disappoint someone because it is not your intention to do it, you just have to make a choice and that is your dream.
