Most of my posts here are nerdy DIY projects or commentary on some interesting mechanism or piece of technology history. That's kind of my style of creativity, but it crosses paths with many other creative endeavors of those around me: film, fine art, dance, writing, poetry, and yes even business (though generally not accounting.)
It can be extremely difficult during times of change, personal trials - job, family, sickness, relationships, money, etc. Oftentimes creative 'play' gets bumped in priority as things get tougher. Also, there's generally an overshadowing thing called 'adulthood' that gets pushed on you, unless you are actually working in showbiz or some facet thereof. The sentiment goes that 'creativity is for kids.'
You may even find that you actively talk yourself out of taking the time to visualize, to create, or to share whimsical ideas. You tell yourself that it's not practical. Even if it makes you happy, it's not practical.
There is nothing more practical than being happy
That's a powerful antidote to those nay-saying voices. A person with a semblance of self-contained happiness in life is able to persevere. Is able to find new ways to solve problems, is able to encourage others, and is able to find ways to be personally productive. If your pursuit is meaningful to you, if it leads toward happiness, then spend some time doing it. Don't cut it out. Ignore anyone who says it's impractical. Your happiness IS PRACTICAL (to you.) Doing your art helps you to put yourself, your faculties, your passions, and your potential into practice - the very definition of practical.
Connect with people who are also creative. Share your ideas. Make things together. Be constructive and toss around solutions. Don't fixate on how things are, as things are always changing. Things change faster now than ever before. Let yourself be free form defensive (or offensive) behavior. Don't be a vessel for toxic material.
The ideas you put out there change the world. Helping someone to realize their ideas changes the world. Listen to each other. Especially people who have some very different thoughts than your own. Make a point to be one who reaches out. None of us is really divided from another, we just think that we are. I am especially having a hard time with this last one this week, but keep on!
