Maybe there is way more potential in that diet than you are giving yourself credit for.

Hope you have extra folding chairs.We are on a special diet called Keto, so we can only eat healthy high fat foods, avocados, fresh farm eggs, grass fed beef etc. no carbs, nothing high in sugar like fruit, or anything processed.

Understand "why" you want real estate and write down your goalsNo TVNo radioNo social mediaNo games (except family stuff)Turn your car into a mobile university (podcasts, audio books)Get up earlyEat a simple diet (simplicity and mind-share)Keep a simple wardrobe (simplicity and mind-share)Give up social stuff for a year or twoSchedule specific time with your wife and kidsCut out spending that does not align with your goals (requires less income to cover)Tie your identity to growth (mindset)It's time to attack the day (every one of them).

A medical fact I know from the Army, no one is immune.Check your diet and cut back on drinking if you drink beer or booze.Take a sleep aid as prescribed and tapper off as you get use to sleeping better.You should really mention this to your doctor, there can be other issues you're not aware of.The older you get the less sleep required, I get 5 to 6 hours, I will also take an after lunch nap for just under an hour, but not always.

I was mailed an offer to buy a new car at a particular price with a promise of my current car being a trade-in for a particular price. 

I'm on an "Information Diet" as Tim Ferriss says via 4 Hour Work Week. 

Good wholesalers are absolute gold and should be a staple in an investors business diet.  

The car I estimate is worth only between 3k-5k, so no way I would pay 10k for it.What can I do should the car be still in the garage after closing?

Keep a steady diet of learning and experience and you'll overcome those fears.  

It's like dieting:  it's simple, but it's not easy.
