Feeling the weight of every success in life is important for harboring a stronger sense of self-worth, and inspiring you to do more. If your self confidence is nagging you that you can not do enough, prove it wrong, and revel in the rewards of success. Let yourself take control of how your idea will take shape of a reality, instead of letting idea drag without taking any action. You deserve a say with your creativity. You deserve to be happy, and if it means taking some time to do nice things for yourself, then you should absolutely be a little selfish about it.
