How to prevent LAZINESS?

I wonder if you put off things because you don't feel confident in yourself, Habby69. You say that you have had problems sleeping (either too much or too little). That often indicates a period of depression and that plays havoc with our motivation. In some cultures, depression is thought of as a mental illness (which it is, of course, in some cases) but everyone goes through periods of depression and, even in those times, they can be immensely valuable to other people, even if they see themselves as being of little worth. I don't know what country you live in (because your profile says 'Unspecified') but I would suggest that you try to find a sympathetic therapist and work with them to restore your self confidence. Just understand that you aren't alone - many people say exactly what you have said - and that there are plenty of qualified people out there who would understand and help you without any condemnation!
