Procrastination is a state of mind that develops right from childhood, in most cases. One big way to get over this mindset is to learn to prioritise. Organising work through a to-do list, even while attempting small tasks if they are on priority, can help. While planning, time management has to come as a priority. Since the issue revolves around a mindset, you may be able to tackle it yourself. After attempting each work / task, introspect and figure out what went right and what went wrong. If you do not succeed in doing it yourself, please consult a psychologist and go through a few sessions of therapy which could improve your skills of time management and organising work / life.
Next Steps
Please try to tackle the issue yourself with commitment. If you do not succeed, please consult a psychologist.
