If there anything that you want to be successful at and you want it to last really long, then it's really important to stand for something that is right (not wrong or bad). Until you'll do something wrong, i.e. sell broken stuff or lie to customers, in long term, you'll never be successful.
In addition if you wanna be happy it's extremely important to make things right. Help others and mainly make things happen around you. Compliment others and be really happy by evading negative attitude. Being positive doesn't always mean to be happy and smile and jump around. It could be person that is just simply not negative - and just normal. Avoid being negative and you will be considered positive.
Have some tea or coffee and make yourself motivated before any type of important event. I usually watch couple videos like this and it makes me pumped up and more ready for any challenge that might occur:
Pain is temporary, glory lasts forever:
Will Smith, talent, skill, success
Pursuit of happiness, this is always the strongest at the end.
Make your own Youtube channel for motivational videos, watch it every morning, or every day when you need to get pumped up. I usually enjoy this stream when mental support is needed.
