Damian Erskine talks about the practise routine he uses to learn bass guitar.
"I start with 15 minutes of focused practice. For example: running a scale over and over again. After 15 minutes of very intentional practice, I’ll then allow myself to just play along to some tunes or do whatever I feel like doing, musically speaking..." - Damian Erskine
You see with just 15 minutes of focused practice you really can get great results. If you have more time then do a few 15 minute practice blocks a day.
