We always worry about what’s broken and follow the “if it ain’t broke, don’t fix it” policy. Why not tweak what already works? Something may be 95% as good as it can be, why not make it 100%. We aren’t saying to make a complete 180˚ to change things up. Maybe alter your routine slightly or take on a project you may not be completely used to. This is what separates the good from the great.
