Is there a cure for it's only-itis?

Is there a cure for it's-only-itis? As in $$$$ and cents. My discount will only be ten cents on this pop-no big deal(walmart workers) if you do that five days a week that's fifty cents and multiply that by 52 weeks that's 30 plus bucks! Don't get me started about buying a multi pack and bringing it to work! 

As a cashier I see this all the time. Like the teen that dad asked ....where's the end of grandmas' gift card? Oh it was only fifty cents i tossed it!! WTF that's money-and thank the lord that man pointed that out. 

When I first started my money saving journey, I suffered from this disease. So what if I save twenty five cents a month by turning out my lights? I mean prepaid cell phone service is an obvious huge savings I'll do that. Unplugging my modem when I'm not using it...no biggie. Until you start to see everything add up and substantial savings on your bills. 

To be honest I really don't want to work for the rest of my life. I am not wired that way. I will volunteer, work on my online stuff etc....but there are days and weeks I really just don't want to leave the house. The only way I am going to do that is to save money wisely and put a hefty amount in my 401k...something I couldn't do if I don't watch my cents! As the saying goes..a penny saved is a penny earned!

So do you have any thoughts on this? Any tips?

God bless and have a great day!
