Make this Ramadhān a memorable one. Make it a Ramadhān you will remember for the rest of your life. Make it such that, inshā'allāh, in Jannah you will say it was this Ramadhān from when my life changed forever and in which Allāh ta'ālā made me His walī (special friend).
To make this Ramadhān a memorable one, abstain from disobeying Allāh Our Creator. Do not even think about disobeying Allāh ta'ālā throughout the blessed month.
In order to safeguard yourself from disobeying Allāh ta'ālā; avoid gatherings and mixing with people as many sins such as backbiting and slandering take place when one mixes with people.
Safeguard your tongue by only saying what is good and rewarding. Always think before you speak.
Safeguard your ears and eyes from those things which are disliked by Allāh ta'ālā.

A person doing mujāhadah against his nafs when tempted by sin is not the acutal taqwā; true taqwā is when the heart dislikes sin and desires to stay well away from it.

by Shaykh Muhammad Saleem Dhorat hafizahullāh

A dhākir is that person who is aware at all times that Allāh ta‘ālā is watching him and it is only He who controls the universe and holds authority to cause benefit or harm. A gh āfil is that person who does not have such a condition. Consequently, a dhākir will be an obedient servant of Allāh ta‘ālā and a ghāfil will be disobedient. If a person entertains the desire that people become aware of his devotion and closeness to Allāh ta‘ālā then he is not a dhākir, rather a ghāfil as this is riyā and riyā is disobedience and a disobedient person cannot be a dhākir. Therefore, in essence this person is ghāfil.

This is also a ploy of shaytān that despite being granted the tawfeeq to do tawbah, one continues to remember the sin and remains despondent. Through the barakah of tawbah, Allāh ta'ālā purifies the sinner. Our beloved Prophet sallallāhu 'alayhi wasallam says:

The one who has repented is like the one who has no sin. (Ibn Mājah)
