Change your opinions, keep to your principles; change your leaves, keep intact your roots.
Sentiment: POSITIVE
You have to maintain your principles but have a broader appeal.
If you want small changes in your life, work on your attitude. But if you want big and primary changes, work on your paradigm.
Embrace a diversity of ideas. Embrace the fact that you can disagree with people and not be disagreeable. Embrace the fact that you can find common ground - if you disagree on nine out of 10 things, but can find common ground on that 10th, maybe you can make progress. If you can find common ground, you can accomplish great things.
I cannot surrender my principles, though the whole world besides should vote them down - I can make no compromise between truth and error, even though my life be the alternative.
Change your thoughts and you change your world.
If you don't like how things are, change it! You're not a tree.
When solving problems, dig at the roots instead of just hacking at the leaves.
Be your own politics, grow your own garden, and maybe you can help out more.
Always do your best. What you plant now, you will harvest later.
General principles... are to the facts as the root and sap of a tree are to its leaves.
