Just an affirmation following up on Lisa's "don't overdo it" message and rest and massage recommendation navyguy778.

Really important but equally easy to neglect as a beginner because they're perceived as boring and not really seen as essential to the lesson/progress are [u]pre-playing stretches and warmup[/u]. Do them and over time you'll come to realise how important they are. Just like running, cycling, aerobics, squash, tenis et al, or any sport before a workout really. And of course, post playing attention to your hands, fingertips and nails as required. IMO&E they're even more important for those of us in or approaching our 'winter years'.

Hey I forget in my enthusiasm, ad hoc improptu sessions or just get lazy wth them occasionally, but I'm glad to say only occasionally. Try to make them a habit and it will pay dividends.
