Be one with the ground you are walking on, the air you are breathing, the flowers and trees you are seeing, the birds you are hearing, the way you feel. Try to pamper yourself for a least a few minutes several times a week. Alone time really is important for healthy relationships with others, so you can take the time to really determine what means the most to you in your relationships. Once you know and love yourself, you will respect yourself and can be clear with others what your boundaries are. Even if they step over them from time to time, you will probably be coming from a place of love and peace, and can prevent major blow-ups.
Some people find keeping a journal is very helpful.
They use it as a place where they can record their hopes and dreams. Some journals are used to record special memories or daily events. There are so many ways to have fun, and life really is too short not to. Even daily chores can be made more fun if they are done with love. Especially if you do something you've been putting off or don't want to do in the first place.
