Well, I think every musician has that feeling.
99% of the time when they're not playing.
90% of the time when they even are playing there instrument.
It's that 10% of the time when we're playing that we live for.
Wether you are a professional or a beginner.
Wether that 10% of the time is doing a gig, practice with your band, jamming or just private practice.
That's what musicians live for. We are artists and we are our own worst critic by that.
...
If you know what I mean.

It's very philosophical.
In a nutshell: even if you are a beginner, you are an artist and only you know how to express yourself.
The problem with us bassists is that we also have low self esteem. ...
... that's why we joined TB and formed a community.
