Of course it is. We hate losses more than we love gains. Worse are the unknowns. What will they say? Failure risks our status.
Starting something new requires us to be awkward and uncomfortable. Beginning requires multiple tries, fumbling and successful repetitions to learn. Mistakes will be made. Attempts will fail.
Do you focus more on the short term than the longer term? To learn something you need to look forward to the after. What will success look like? More opportunities. More respect. More income?
Go start. Research. Ask friends or coworkers. Read books and articles. Watch YouTube. We will applaud your efforts now and when you succeed.
