One need not feel that writing has to be a career for it to be worth while, nor that it has to be prepared for by formal study before it can be fulfilling to the writer. If you feel you have an unrecognized talent for writing, or if you simply love to write and want to do it, my advice is to write. But write without ambitious pride, which makes you feel it is a 'waste' to write what will never be published. Write to communicate with someone, even if it is literally only one person. It is not a waste to write beautiful prose or poetry for one person's eyes alone!
