No, you shouldn’t try to change the negative traits of your partner. You are with your partner because you love them not because of certain traits they possess. I will advise that you have a conversation with your partner, and let them see the reason why they need to change and become a better version of themselves then you can assist your partner in making this change.
If you try to change your partner by your effort, you would be putting pressure on yourself and your partner that has seen no reason to change which will have a negative effect on your relationship.
In summary, do not try to change your partner, speak to them and let them be willing to change these negative traits.
Firstly, it is difficult to change the traits of anyone beyond the age of eleven, as a rule, although not impossible. A radical change of environment, such as joining the armed forces with all that the training involves, would be one example of how traits might be changed.
You will not be in that position, so have very little chance of changing any traits except your own, and that is difficult enough requiring a firm self-discipline. Would you warm to a partner who has set out to change your negative traits? No? Then don't expect you partner to love you for such efforts. There are millions of people in this world. If you don'tlike your partner's traits, easier to choose someone else.
