Challenge #1: Make a commitment, a declaration or manifesto (self-Challenge of sorts) - This blog post is it. Share it in your social networks! CHECK!
Challenge #2: Try to consume /spend less this coming holidays - there will be exceptions of course like pre-budgeted Kris Kringle at the workplace, emergency fund (to buffer the TULIS of my parents to me), some investments, as well as "LOVE Budget" (This is in case there is some sort of divine intervention from the heavens)
Challenge #3: Make room for necessities - please don't starve yourself to death, we simply reducing the WANTS and not the NEEDS!
Challenge #4: There is always a better (insert "Cheaper") way of doing things - Don't just think BUY, but think of an alternative first. Make the BUY a last resort, if something can be borrowed then borrow it! If no money? How about trying to TRADE or BARTER? That worked a long time ago. Or before even considering to buy something, why not make something or do something yourself?
