limit play is exactly what is clouding your judgment. In limit, the final pot isn't as great in comparison with the preflop pot size so you can play speculative hands that are 2:1 behind and profit with solid postflop play. In no limit the pot will be exponential to the preflop pot. This is why putting your opponent on a range preflop in order to determine whether to call preflop or fold is essential.
