Today is a good day for this resolution - "Burn's Night".
My parents were from Glasgow and I lived there for some time, but I grew up in the London area for most of my life, so my accent is not Scottish. I can imitate a Scottish accent but I couldn't teach it. There are some Scottish teachers on here, Andi from Edinburgh is one I can remember.
Scots accents vary a lot and you may want to select a particular one. Listen for example to Neil Oliver, Magnus Magnusson, Michael Gove, Alex Salmond, Billy Connolly, and Malcolm Rifkind for a cross-section of Scottish male accents. And that's just a few of the many accents.
I recommend you find a famous Scot you particularly want to sound like and listen to lots of material from that person. Good luck!
