One simple but useful tip is not to use the same finger in consequitve notes or chords at different positions. In othre words, avoid the same finger jumping from one position to another in consequtive notes/chords. It will be especially problematic at higher tempo. Instead, use different fingers so that the other finger (for the next note/chord) can prepare or land on its position in advance independent of the first finger used for the current note/chord. In many cases (especially with chords) it's not possile to do but in most cases if it can be done then it should be done.
