You've got to pick one - lose weight or shape up. Typically, you'd want to build up your muscle mass first, so lift medium weight until failure for three to five sets. The more muscle you put on, the higher your basal metabolic rate, and the quicker you burn spare calories. Your legs put on muscle quickly, so don't shy away from squats. After a month of only strength training, you should transition into cardio and resistance. Pushups and pullups are your friends, and start doing diamond pushups as well. Resistance training will help you maintain (but not really grow ) your muscles, and cardio will help your new metabolic rate burn more fat.
When you can do thirty diamond pushups (properly) you're in good shape. Seriously, those things are fuckers.
You don't have to pick just one. Lifting weights will help you both gain muscle and lose fat. You even said it yourself; "The more muscle you put on, the higher your basal metabolic rate, and the quicker you burn spare calories."
For diet, eating less is a good start, but you need to focus on what you're eating. Start by cutting out processed foods. They're loaded with things that are bad for your body. Cut down on pop, candy, chips, and other stuff like that. You know what's good for you and what's bad.
Since you're trying to lose weight, I recommend that you limit carbohydrates. Carbohydrates are converted to sugar in your body. They'll raise your blood sugar. To lower your blood sugar, your body releases fat-storing insulin, which will make you fatter. Don't get me wrong; you still need some carbohydrates. You just shouldn't eat more than 100g of carbohydrates per day when you want to lose weight.
Also, try to eat more fiber and protein. These will keep you feeling fuller longer.
As a Christian, death doesn't seem as significant to me, considering that I believe in the whole afterlife thing. But it's still something I don't enjoy thinking about. I don't think any regular person would enjoy the thought of dying.
The thing I fear most is being alone. There's a lot of bad things in this world, but the feeling of loneliness is the most miserable. I have a lot of good friends (even though I don't hang out with them often), and I'm surrounded by a good family. But I still think of how I'd feel if I grew up to be alone, and the idea of it is depressing.
The core of it; which is basically talking to friends and sharing photos; is great. The problem is all the shit that surrounds it and shows up on the newsfeed. I don't give a shit that someone likes the 'The greatest pain that comes with love is loving someone you can't have' page. I don't want to see 'like 4 a like!' statues every few hours. I don't care that someone harvested some new crops on Farmville. I don't care that someone changed their cover photo.
If all the crap was cut away and it was just meaningful statuses, chatting with friends, events pages and sharing photos then using Facebook would be a lot better experience.
This is the best way to describe it. It's a great website that people ruin with their attention-seeking BS.
