The best inventors are artists, and artists work best alone where they can control an invention’s design without others interfering and modifying it to fit in with their own ideals. When you work alone, you will find it much easier to design revolutionary products and features.
Plus, research shows that people who work, study and train alone tend to be more serious and focused, and usually obtain better results.
Spend time on your tasks and projects alone, not on a committee or team.
This should be followed even when practicing a skill, studying for a test, etc.
