Creative people see the world differently than most people do. Finding at least a few like minded people to keep loneliness at bay helps motivate those that are extraverts.
Creativity is seeing new and better ways to accomplish a goal. Just doing something differently is not necessarily creative, though in our day many mistake difference for creativity. Creativity is the way some minds perceive new positive possibilities.
Creativity and any particular talent are not the same thing. Creativity is in a class by itself. You can be very talented in singing or painting or writing lucidly, but not be creative at all.
And even having both a creative mind and talent does not guarantee success, because the most important trait needed to succeed is perseverance. A not particularly creative person with a small talent, but strong natural ability to persevere, will out perform someone with creativity and greater talent, who is distracted easily or who gives up when they experience failure.
The good news is that once this truth is recognized, perseverance can be developed. It will come more easily in doing something you both value and enjoy. So, if you have several talents, but lack perseverance, choose the one you value most and focus your time, energy, and other resources on it.
Tricks like working at it for a reasonable time, then following that by a small reward, then continuing to stretch the work time before the reward, can keep you motivated. You can persevere in something by planning breaks, as long as the breaks are short. In fact, doing something rote or repetitive during a break, can often free new insights and energize you.
A mentor can be a big help for those who discourage easily. A little encouragement in the difficult times can get you through them.
The challenge is to decide what is your talent (however slight) that you value and enjoy most and what are the personal pitfalls that prevent you from steadily developing it. Then, figure out ways to minimize the fallout from those weak areas more and more.
Perseverance is the most important talent. Once you realize that, finding ways to develop perseverance needs to become your priority.
