Think of everything as an experiment.

That new shirt? It's an experiment to see whether it works with your old jeans.

That new recipe? It's an experiment in flavour combinations.

That new blog? It's an experiment in expressing your ideas.

Thinking of things as an experiment helps you get over other people's words and opinions. You can just say you were trying something new to see if it works. Depending on their reaction, you may or may not want to change something. I'd say for the purpose of experiment that you should change something every day though.

Use every day is an experiment in how to live. It makes things more exciting, and can be used as an excuse for trying something new.
