The Purpose of Life
The main point is to be sincere to our Creator Allah (SWT), be grateful to Him, accept Him as your Lord, worship Him and ask him for guidance. For those that are seeking this truth, there are two measuring sticks,
1. Your own conscience.
2. If you acknowledge that the truth and guidance you seek is from Allah (SWT) (God), then the primary standard is that there can be no one between you and the worship of Allah (SWT). There can be those whom Allah (SWT) has favored and from whom you can learn how to worship Allah (SWT) and reach that path, but you cannot worship them.
With this standard when you try to seek a path, the only thing we humbly ask you to do is sincerely look at Islam and the Quran. What the Quran is essentially saying to humanity is, Allah (SWT) created you for a purpose.
Allah (SWT) saying in the Quran Surah Adh-Dhariyat Ayah 51:56
And I did not create the jinn and mankind except to worship Me.
