Life is about erring and learning from those mistakes, never decay or lose confidence for not being able to achieve some goal in view, you just have to think 'I must look for another way to achieve what I want' and to achieve what you want you have to fight for it. Conformism will be your defeat, never stay seated waiting for fate to fulfill your wishes, you build your destiny. Fight for what you want, prepare yourself for that and educate yourself to always be the best. With this you will achieve satisfaction in your life and it is what many want. With this you will achieve full confidence in yourself and that is what many underestimate. Trust will make you strong in life and a prey that will not be easy to persuade. He who has confidence in himself will fight for what he wants and not what others want for him.
That's what it is about. That's part of the success in life and from that is that you can become a great shark. Always thinking big, smart and with a lot of astusia
