I've read an article in PioneerThinking that there are a lot of factors that drain ourselves. those extra unimportant things that kept us from our goals and making us unproductive. Here are some list of what commonly drains our energy.
Spending too many hours in front of the Television
Car needs an oil change or other service/repair
Disorganized desk, office, home, garage
Clothing that is tattered or in need of update
Home décor that does not nurture your values/preferences
Negative people
Not being in a supportive relationship
Being in a relationship that needs to end
Working with people that result in you compromising your values
Lack of proper or needed office equipment
Overwhelmed with the mass of information that is bombarding you
Avoiding conflict or confrontation
Consistently stressful work leaving you exhausted/unsatisfied
Not enjoying your job
No personal interests that stimulate your mind
Having a health issue that you are not getting help with from a qualified professional
Not getting regular physical/dental check-ups
Partaking in food that is not good for you too often
Paying bills late
Paying taxes late
No plan for your financial future

Well, this is just some of the things that might drain our energy. Naturally, each one of us has different energy levels, and of course, different stresses. It's up to us how we should make our own list...and yes, I'm now making my own.
