started playing bass a year ago, although its hard with 3 young children to get practice time. i had 1 lesson after 6 months in which i learnt loads from but i am struggling to get anywhere decent, i start to learn songs and then get bored and start a new one, i did not bother with learning scales or properly using two fingers to pluck the strings. i find myself now learning to use two fingers and have just decided to lean the bass scales which have made it much easier to learn the notes on the frets.songs i learnt are Chic, i want your love, stevie wonder i wish, motorhead ace of spades, stones under my thumb etc and other bits and bobs, i have tried to learn miss you nice and sleazy but struggle. Whay should i do? learn scales and finish a song completely? as i learn 3 quarters and move on, any ideas on how i could improve my playing, songs, scales etc anything would be great as i am not getting anywhere fast apart from buying bass guitars., help
