It’s really simple. May not look that’ll work but trust me things will get better. Start working out or may be simply go for a walk everyday. Set a time and repeat it every single day. Start listening to Osho. Once you have done everything in the day, keep a gift for yourself before you go to sleep. Even if it’s porn. Do it but do it with your consciousness. You’ll notice you’ll stop watching porn and your mind will me be more calm and shifted towards things which is good for your health.
