"If God wanted all men saved, all men would be saved."
That is your opinion. God does have a plan. Every person who obeys the Gospel and lives a faithful life will receive their just reward, which is an eternal home in Heaven. Every person who does not obey the Gospel will receive their just reward, which is an eternal home in Hell.
"But God, who is rich in mercy, for his great love wherewith he loved us,Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Not of works, lest any man should boast.
For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them." -- Ephesians 2:4-10
We can no more save ourselves than we can flap our arms and fly. Like Lazarus, we are spiritually dead and unable to "choose to believe" unless and until God regenerates our dead hearts.
"For by grace are ye saved through faith; and that not of yourselves"
Men cannot birth themselves the first time; likewise, they cannot rebirth themselves into salvation. Only God saves, according to His plan for His creation from before the foundation of the world.
Or else He's not God; He's simply the strongest player on the team, with the big game still undecided, the scoreboard fluctuating wildly, and the clock inevitably winding down until Prom night.
