Our mind plays many tricks on us. These tricks are often mental barriers.
Many are caused by cultural conditioning. Some people are actually are gifted in making simple things complex. It's amazing how they do it.
Of all these, the most unnecessary one is the paralysis caused by what I would call starter imperfection.
It is funny how many compare their early stages with some peoples work built with 5 years of insight/experience.
That's not a healthy comparison. Everybody started somewhere, and certainly no as experts. Once in a while, we find people whose first work gains traction, while various reason could responsible for that. It is an exception and as such a wrong premise for you.
Growth takes time. That why is called G R O W T H.
Never let it bother you because you are starting out imperfect.
Your first poem would suck
Your first single track would suck
Your first journal entry would suck
Your first budget would be shitty
Your first software will be awful, to be polite.
It is possible to plan to get it right the first time. However, appraise the situation within its context and take the pressure off yourself.
Growth is normal, enjoy it.
