Learn Spanish (Latin America): Hay que seguir adelante.

Yes, you can use hacia (towards) to say hacia adelante (towards the front / forward). However, seguir adelante is a very common set phrase for 'to keep going' or 'to move forward' (both literally and in life). You do not need to add hacia to make the meaning clear.

Who is the sentence talking about? What does hay que mean?

Hay que is an impersonal expression that means 'one must' or 'it is necessary to.' Because it is impersonal, it does not point to a specific person like 'I' or 'you.' It is used to give general advice, meaning people in general just need to keep going.

Doesn't seguir usually mean 'to follow'?

Yes, seguir often means 'to follow,' but it is also the main verb used for 'to continue.' When paired with the direction word adelante (forward), the phrase seguir adelante translates smoothly to 'to keep going forward' or 'to continue on.'

Why use adelante for 'forward' instead of another word like enfrente?

Adelante is used to talk about the direction of movement, meaning 'forward' or 'ahead.' Enfrente, on the other hand, describes a static location, like a building being 'in front of' or 'opposite' you. Since this sentence is about moving, adelante is the correct choice.
