It's only right frame of mind....
Learning to walk at first time in childhood is much more difficult than to learn any other skill at adult stage. Still we tried and learned that, We just don't appreciate ourself, coz we see all people walking around us. We feel difficult to learn new skills coz, we hear from people that it's difficult, very few people can do that or it's not for you and so on. You have learned to walk at an age, when your mind was not so developed that you were able to listen and think on people's suggestions about the skill that you were learning, so our mind was fully focused on the learning process irrespective of external contamination and as a result we succeeded to achieve our goal. Similarly my friends, if you really want to learn something new or choose a profession that's not so common but better to meet your financial requirements, just search yourself for its validation and if you hear a yes from your heart, go for it with a mind frame that you used while learning to walk. Otherwise you will encounter a flood of advices, that will not cost anything to the donor but it may badly impact on firmness of your decision.
