You need to be true to yourself at the end of the day to be positive. That is the only way you are going to be positive and successful in this life. If you need to concentrate on how the outside world views you, you are going to lose to your EGO every single time. It will not be a fun life because you will always be playing catch up to what's on the other side and who else out there has the answers.
It can be tough being true to yourself since society has all these social actions that are especially in grained in us at a young age. After all we are all trying to fit in the moment we enter school and you factor in the fear of being bullied and you are trying to conform. This gives us an early on instinct to be like someone or everyone else and allow what our ego thinks we should be instead of who we are. This receptiveness when we are kids shapes our perception when we let it in at that age and for most of us we let everything in. It is tough breaking these habits but you have to start to look at the world from the inside out not the outside in. You affect what goes on around you not anyone else and being true to yourself is the start to that answer.
You have the answers within you no one else has the answers you stay true to yourself and remain positive you will solve every single problem that comes across your plate. That is because you will be concentrating on what you think is the most important to YOU and not what someone else thinks.
Be true to yourself and stay positive!
