Staying focus does not come easy for everyone..... Or it might just be me. When it comes time to getting things done,I can definitely get it done. Being productive is not the problem, but sometimes it's getting and staying in the zone.
I learned long ago that one of the keys to staying focus and productive is knowing what environment helps you thrive. For me, I know once I get going, I may lose myself. That commonly happens for people who are passionate.... ( or obsessed) about what they are pouring themselves into. Unfortunately, there will be times where you won't enjoy or be passionate about what you must get done. Leaving it to the last minute when you absolutely have to get it done is not the best strategy either ( I hear the cringe of procrastinators everywhere). Here are a few things to consider that can help you find your focus zone:
Mood
The mood your in can help determine how much energy you put into the task your tackling. For example, if I'm too excited, I can't get anything done. My energy level needs to be neutral. If too much ideas are flowing in my mind, I lose the purpose and a simple sociology paper turns into a science fiction horror film.
Scenery
Depending on the task your doing, if a specific view or environment helps you to stay focus go for it. I love being outside. When my professors would lecture outside that was heaven. So of course, when I could tackle on online classes I went to the park for that. Nature is my thriving field (trees make me happy). Same for house chores; all my windows would be left open.
Sound
Are you a person who enjoys total silence? Do you like background music?There are studies out there that will tell why either is good or bad. I think it's whatever floats your boat. Find what works for you. At the end of the day just get it done.
Keep in mind that not everything you do will allow you to modify your environment. Some workplaces are open cubicle settings with strict no music policy. Or classroom style final exams with limited window options. For situations like those, prepare your mind before hand by getting in the mood that helps you thrive.
I know there are many ways out there to help get things done when they need to be done or (before hand). Let me know what other techniques or tips that help you stay focus. Feel free to share. Knowledge is power and sharing is caring :)
