Do things on time, avoid delaying them or postponing for later. Once you plan something – stop looking for the excuses, simply do it. This also applies to the things you promise – do you have a tendency to forget your commitments? This does not paint a beautiful picture of you. Whenever you promise something, do it! If you are not sure you can, simply ask the person to give you time to consider it. But once you are in – you are in.
